Summary
Brief summary (as posted)
The trial aims to evaluate the effectiveness of a novel web-based intervention (Optimune), which was designed to introduce relevant cognitive-behavioral therapy (CBT) techniques to women with breast cancer who are past the active eradication phase. The present study will test the hypothesis that Optimune has an impact on lifestyle parameters and psychometric outcomes. Therefore, 360 woman with breast cancer will be recruited and randomized to two groups: (1) a control group, in which they may engage with any treatment (Care-as-Usual, CAU) and receive access to Optimune after a delay of 3 months (i.e., CAU/wait list control group), or (2) to a treatment group that immediately receives 12-month access to Optimune and may also use CAU. The primary outcome measure is the effect on quality of life, physical activity and diet three month post-baseline.

- description
- Optimune is an web-based psychological intervention for women with breast cancer. Beyond established CBT techniques targeting depression, anxiety, and fatigue, this intervention specifically includes elements that have shown effects on markers of immune status and inflammation, including sleep, stress management (e.g., mindfulness-based techniques) and lifestyle optimization (dietary and physical activity advice). Content is continuously adapted to users' concerns and needs. It contains interactive dialogues that can be accessed via computer or smart-phone, illustrations, audio files and motivating text messages. Optional daily text messages with motivational content accompany the program. The program can be accessed for 365 days after registration.
